Comparison of Developing vs. Non-Developing Tropical Disturbances,

Abstract

Developing and non-developing western North Pacific tropical disturbances are investigated and compared utilizing Defense Meteorological Satellite Program (DMSP) and rawinsonde data. Quantitative measurements of deep convection and cirrus amounts from the satellite visual and infrared data indicates that no large deep-convective difference exists between these two classes of disturbances. In addition, the daily variability of deep convection was determined to be large in both the developing and non-developing disturbances. Implications are that the amount and intensity of deep convection is not well related to disturbance tropical storm genesis potential. Genesis appears to be related to the special positioning of the deep convection and surrounding wind fields. When genesis occurs, the deep convection appears to act indirectly to warm the tropical disturbance by means of dynamically forced subsidence. Documentation is provided to support this hypothesis.
